Nandrolone Decanoate is a 19-nortestosterone most commonly known as Deca-Durabolin. Deca-Durabolin is simply the trade name given to Nandrolone Decanoate by Organon and the common name most largely associated with the compound. As there are many Nandrolone forms this particular one is attached to the long Decanoate ester giving the compound a very long half-life of approximately 15 days; this is about as long as a half-life will be with very few anabolic steroids carrying half-lives that extend beyond this point. As a long ester base steroid the effects of Nandrolone Decanoate are slow yet steady and long continuing after use is discontinued; as is with most long ester based anabolics detection time is extremely long and as the Decanoate ester is one of the longest esters detection time stretches to the 18 month mark. This simply means if an athlete supplements with Nandrolone Decanoate and discontinues use, if tested for anabolic steroids he will indeed fail the test up until 18 months have passed from the final injection.

By its nature Nandrolone Decanoate is extremely anabolic with very low androgenic properties; however, androgenic traits do exist but only to a slight degree. As is with most anabolic steroids it will suppress natural testosterone production, however it will do so at a much higher rate than most other steroids. This makes testosterone supplementation necessary when the Nandrolone compound is used; one dosing of Nandrolone Decanoate will completely halt all natural testosterone production, even a mere 100mg injection.



As a very long ester based anabolic steroid the initial effects of the compound will not be noticed until at least 4 weeks of use have been applied. Because Nandrolone Decanoate is so slow acting 8 weeks of use will prove to be the minimal time frame if one wishes to reap a reward of growth with 12-16 weeks of continuous use being far more optimal but the average time frame for most people is generally 12 weeks.

There is an important note; as a slow and long lasting anabolic steroid, once discontinued the effects of the steroid will continue to manifest them far past the final injection; as much as 25% of the active hormone will still be functioning in the body 30 days after the final injection. Due to this long lasting effect most will necessarily wait approximately 3-4 weeks before post cycle therapy treatment begins after Nandrolone Decanoate is discontinued; of course we’re assuming in this case all anabolic steroids have ended by this point. However, a more proper course of action would be to end all Nandrolone Decanoate use and continue testosterone therapy approximately 2-4 weeks before the total cycle is complete. If the cycle ends with long ester based testosterone, such as Testosterone-Enanthate or Testosterone-Cypionate a 2-3 week waiting period will suffice before post cycle treatment begins. Conversly and this is preferred for optimal results, if the cycle ends with short ester based testosterone, such as Testosterone-Propionate the individual can begin post cycle therapy a mere few days after the final injection; this is assuming all Nandrolone Decanoate use ended at least 2-3 weeks before the total cycles end. Keep in mind, the sooner we can begin our post cycle recovery the sooner our natural testosterone production will begin again and the more gains we’ll be able to hold onto and the healthier we’ll be.
